  • Hydraulic influences on pool morphology : a laboratory investigation

    Creator:
    Frizenschaf, Jacqueline
    Abstract:
    A flume study was conducted to investigate the influences of changing hydraulic conditions on the bed morphology of a scoured pool. During a simulated storm runoff event, responses of the pool were tested under different conditions: clearwater flow, sediment supply at steady rates, and two different sediment mixtures of the...

  • Interaction of water waves and deformable bodies

    Creator:
    Broderick, Laurie L.
    Abstract:
    A time-domain model was developed to predict the fluid/structure interaction of a three-dimensional deformable body in a fluid domain subject to long-crested finite amplitude waves. These nonlinear waves induce transient motion in the body. In turn, the interaction of the body with the waves modifies the wave field, causing additional...

  • Abiotic and biological transformation of TBOS and TKEBS, and their role in the biological transformation of TCE and c-DCE

    Creator:
    Vancheeswaran, Sanjay
    Abstract:
    At Site-300, Lawrence Livermore National Laboratory (LLNL), CA, trichloroethene (TCE) is present along with tetraalkoxysilanes such as tetrabutoxysilane (TBOS) and tetrakis(2-ethylbutoxy) silane (TKEBS), as subsurface contaminants. Intrinsic transformation of TCE to cis-dichloroethene (c-DCE) was observed in the groundwater at locations co-contaminated with TBOS or TKEBS. Attenuation of TBOS and TKEBS...

  • Disinfection of settled and unsettled trickling filter effluent by chlorination

    Creator:
    Monroe, Darrell Wayne
    Abstract:
    The colicidal efficiency of chlorine in both settled and unsettled trickling filter effluent samples was determined by means of a series of tests in which each sample was analyzed, at given time intervals, for suspended solids, pH, residual chlorine (orthotolidine and iodometric) and coliform count. A dye-tracer study, using Rhodamine...

  • Numerical modeling of full-coupled fluid-structure interaction

    Creator:
    Yuk, Dongjun
    Abstract:
    A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-ε model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid...

  • The degradation of kraft pulping wastes in estuarine waters

    Creator:
    O'Neal, Gary Lewis, 1938-
    Abstract:
    The degradation of kraft pulping wastes in estuarine waters was measured in terms of the following parameters: five-day 20°C B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel (Mytilus edulis L.). The waste tested was the total effluent from a combined pulp and paper mill producing 430 tons of...

  • Consumptive use of surface water by Willamette Basin municipalities

    Creator:
    Mittelstadt, Richard Lee
    Abstract:
    The consumptive water use of six cities in the Willamette Basin of northwestern Oregon was evaluated for the period 1960-66. Consumptive use ratios were obtained by analyzing data from monthly water supply and sewage flow records. The average annual consumptive use for the six cities was found to be 26...

  • Effects of imbedded perforated pipes on permeability of gravelly stream beds

    Creator:
    Chu, Eddy Tak-hing
    Abstract:
    Perforated pipes were buried in the gravel bed of a laboratory stream, extending upstream from a simulated riffle in order to study their effect upon mixing and interchange of stream water and intragravel water. In the absence of such pipes the drop of energy gradient of the stream was concentrated...

    Al-Swailmi, Saleh H.
    Abstract:
    Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...

  • Penetration resistance predictions for driven piling

    Creator:
    Hansen, Lawrence A.
    Abstract:
    This paper presents a method of predicting penetration resistance for driven piles, using known driving records for driving the same type piling in similar subsurface conditions. As known driving records are not always available to the analyst, a method was also investigated using soil data only. The analytical tools employed...
